You can upgrade at eurostar.com. Just sign in to Manage booking to change your ticket.

Upgrades are subject to availability and you will need to pay the difference in fare (per person per leg of journey).

We're not able to offer upgrades to Business Premier on routes to or from London, and we can't offer upgrades to Premium on our routes between France, Belgium, the Netherlands, and Germany.
